First of all, the communication with Ms. Atchara was perfect. She is on line for give you all the answers and advices that you can need and once at the big and clean room will be there Ms. Aon for any thing.
For us the location of the room - the building - wasn't a problem, because it is very easy to get there at any time: you are very close to Wat Saket Temple, that means that you have a big and knowing reference for all the drivers.
Also, you are walking distance of Khoasan Road at not far for the others main attractions, as a Royal Palace, the Wat Poh temple and the river.
The quietness of the neighbourhood is excellent if you are looking for the necessary silent.
